You can easily use a PC's printer port for serial-EEPROM programming. You can use a device-programmer circuit used to program the MicroWire serial EE-PROM 93CXX (Figure 1). The circuit is so simple ...

Turn on the EMP-20 Programmer (in back). There is a power light next to the ZIF socket (Zero Insertion Force) and the ZIF’s handle should be straight up. Set the "T" switch on the shelf next to the ...

We all know that solderless breadboards have their limitations. All that stray capacitance can play hell with circuits, especially high-speed stuff, but they’re so darn useful that avoiding them in ...

A special adapter designed to handle the recently introduced Miniature Array Package (MAP) from Atmel Corp. is aimed at simplifying the programming and testing of Atmel's AT24C01A ...

The [IMSAI Guy] has posted a follow-up video with all the details of how he programs GAL22V10 chips in the modern era. We noted that this was missing from his stepper motor project a few days ago, and ...

In the past, many analog products underwent zener and link trimming operations at the device sort stage to tighten the distribution of selected parameters, such as output voltage. The trimming process ...

Microchip’s latest addition to its 8- and 14-pin 8-bit PIC microcontroller (MCU) family is the PIC12F617 which features 3.5kbyte of self-programmable flash program memory. It also has peripherals such ...

EEPROM memory, which recently celebrated its 50th birthday, continues to defy obsolescence. Despite its age, EEPROM remains a mature, reliable, and affordable technology for many electronic systems.
